Specification of Letters Patent.

Patented July 5, 1921.

Application filed November 22, 1919. Serial No. 329,793.V

To @ZZ whom t may concern:

it known that we, GEORGE WT. li/icLnAN and EDWARD J. Suor., both ci...ens of the United States,both residing at New rleans, in theY parish of Orleans and State of Louisiana, have invented new and useful Improvements in Checking Devices, of

which the following is a specification.

Our present invention pertains to checking apparatus, and it contemplates the p-ro vision of a device whereby a person passing through the same will register such fact and hence when used as an adjunct to a freight car, ship or the like the number of trips made by a person into such places will be accurately indicated on the register of the device and hence the necessity of employ--- Y ent, especially in view of the fact that each laborer generally carriesy but a single bunch of bananas on each trip into the ship.

The invention in all of its details will be fully understood from the following description and claims when the same are read in connection with the drawings, accompanying and formingpart of this .specification, in which: I

Figure i. is a perspective view of our novel device, showing the platform and checking apparatus arranged thereon.

liig. 2 is a section of the shaft on which the checking arm revolves and also showing the pins that limit the movement of the checking arm.

Fig. 3 is a 'longitudinal section of the shaft and cross-arm and showing the connection of the checking arm.

Fig. 4e is a detail view of the checking arm and spring clip for restricting movement of the said arm.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Our novel device is mounted or otherwise secured on a portable platform lvthat is equipped with the runway 2 and is mounted on the legs 3 whereby the platform may be placed alongside a car door or the like; it

, the

being well to bear in mind that the runway will be placed parallel with respect to the car or car door opening. lt is well to bear 1n mind however, that the platform may be equipped with legs as in the present instance or with other means to el vate the platform in the discretionl of the manufacturer.

illustrated in the drawings, the platform `1s equipped with a rail 4 on which the hooks of the runway will rest, and arranged on the platfomiL we provide a passageway formed by the upstanding frames 5 and 6, The frames 5 and 6 are preferably arranged on the platform as illustrated and in this connection it will be apparent that the frame does not entend th `the full depth of the platform. ive make this provision so that a laiy )rer may turn to the left at the second upright and travel in the direction of the arrow. The side A of the platform is placed against the opening of the warehouse, car or the like to be loaded and when the laborer has attended to his mission in the warehouse or the like he will return in direction of arrow B and thence down a runway, (not shown) similar to the ruuw ay 2 that "is arranged on the long rear side of the platform i. The frame 6 has the runners 7, 8, 9, l0, ll, l2 and i3 and le; and secured between the runners 7 and S is our novel checking apparatus.

The said apparatus comprises a checking arm'having an end l5 that normally extends across the passageway between the frames 5 and 6. y The sai-d end 15 is threaded c or otherwise vsecured to a rotatable cross piece 16 that is movable around a shaft 1T thatin turn' is'mounted -in blocks 18 and rihese hlocksl and 19 are screwed or otherwisev fastened into thev runners Tand 55, respectively of the frame 6.

@n the opposite side to that inwhich the checking arm l5 is secured in the cross piece 16, we thread a short arm 2O that is slightly reduced in size at .its outer end as appears in Fig. 3 for an important purpose hereinafter set forth.

As will be seen by reference to Fig. l, the post 21 of the frame 6 vis provided with a spring clip comprising spring leaves 22 and 23 that are secured tothe post 2]. by interposing plates 24 and 25 between the inner ends of the leaves and then passing pins 26 through the leaves and plates. At their outer ends the leaves form a substantial Y, and the upper leaf 22 is provided at a point slightly in rear of the Y With a recess 27, Fig. 4r, to receive the slightly reduced end of the arm 20. The leaves are further held in proper positions by the bolt 28.

Secured to the outer end of the arm 2() is a chain 29 that passes over a pulley 30 and is secured to a chain that in turn connects with the ordinary Welldrnovvn register 31, such as for instance those used in a street railway car.

In order to prevent the arms 15 and 2O from turning farther than necessary about the shaft 177 we provide between the blocks 18 and 19 and at either side ot the cross arm 1G, the stop pins that by preference are covered with rubber tubingv 33. (See Fig.

ln the practical use oilt the device the platform is placed with the side A abutting` a car door opening or the like with the runway 2 in its proper position on the rail l oit the platform.

VVhen a laborer carrying' merchandise or the like enters the passage way between the frames 5 and (3, his body will strike the checking arm 15 whicb'vvill move in the same direction in which the person is traveling. Naturally the cross-piece will rotate on the sba'ft 17 and move the arm 2O out of the recess 27 of the leaf 22 and in the direction opposite to that oit the arm 15. riihe chain 29 being attached to the arm 2O will be placed under tension and pulled l'orward thereby causing the register to operate and register the passage or the laborer or other person through the device. The arms 15 and 2O will. be limited in their movements not only by the spring 29 but also by the rubber covered pins 32. Said pins 82 will, because of their resilient covering;- assist the spring to quickly return the said arms 15 and 20 to their normal positions, a'tter the body ot the person has released the arm 15. The recess 27 Will tightly hold the arm 2() against casual movement and the clip will prevent a person from attempting;- to return through the passage Way.

0f course it is obvious that the arms 15 and 2() may be placed at any point throughout the height oi the frames, and in tact as many arms 15 and 2O may be used to prevent a person from crawling under or climbing over the arm 15 and thus fail to register his entry into the ship or ear.

7e Would have it distinctly understood that the arms, clip and crossarm as Well as any other elements ot' the device may be formed of Wood or metal as occasion demands.

rlhe device as a Whole is simple in construction and very inexpensive to produce and maintain and will eliminate Jthe require-- ment for a checker and will also be reliable in its recordingwhich is not the case Where an attendant is employed.

Such changes in the relative size and arrangement of parts may be made as 'liairly Jall Within the scope ot the appended claims.

Having described our invention, what We claim and desire to secure by Letters-Vat ent, is:

1. ln a checking; device, the con'ibinatiou of a revoluble member, pins adjaf'ci'it the revoluble member. a checking` arm haif'ingg one end secured to the revoluble member` an arm secured to the revoluble member directly in rear oi the checking' arm, a register communicatiug With and actuable by movement oi" the arms; said arms being limited in their movements in one direction by the pins adjacent the revoluble member, and a spring;I clip so constructed and arranged with respect to the second arm that it limits the movement ot the checking arm and second arm in another direction.

2. In a checking` device, the combinatimi ot a revoluble member.j arms secured to the revoluble member and movable therewith, a register communicating with thearms, pins lor limiting the movement oi the arms in one direction, and a clip that prevents movement in the opposite direction.

ln testimony whereof We have hereunto set our hands in presence of two subscribing Witnesses.
